PRODUCT DESCRIPTION

In this video, which is a supplement to my Chromotography Lab, I walk through the process of taking 8 seemingly identical black water based markers, and through a process called chromotography, separate the inks in the markers into their individual chemicals, showing that they are indeed, NOT identical.

This process shown is an extremely basic example of the methods used by forensic scientists to identify substances found at crime scenes....without the million-dollar machines.

The video explains the basics of how chromotography works, and can be used as a TAG/GATE type activity for students, as a lab make-up video, or for teacher instruction.

For this item, the cost for one user (you) is $2.50.
If you plan to share this product with other teachers in your school, please add the number of additional users licenses that you need to purchase.
Each additional license costs only $1.25.
